But the top of the foundation is supposed to be finished off so that water runs away instead of accumulating around the bolts. That's very different from having rebar protruding into wet soil. ______
At what point are they rusting? if this is a US Tower, my understanding is that the only exposed part should be the threads that protrude above the nuts. It's easy enough to spray some rust preventat
I have never tried it, but in the electrical dept. of Lowe's the other day I saw "CRC" brand sealant in a pressurized can. Red in color and especially designed for electrical work, it presumably does
The contractor came on Saturday and started digging the 5' x 5' x 7' hole for the foundation for my US Tower HDX-555. He used an oversized post-hole-digging attachment on a Bobcat, then squared it ou
I found Kellem grips at my local Crescent Electric location -- and they seem to be pretty much nationwide. Also at http://crescentelectric.com Alan NV8A ______________________________________________
I have the 2004 Rohn catalog in PDF form, but I can't remember where I found it. Page 107 has a table for bracketed 25G. For a height of 40ft it shows *two* brackets, one at 15', the other at 30'. Th
I am still waiting for my tower to be delivered, but I am planning to do things "the right way" for the coax and control cables -- using Kellem grips, which all the "real electrical suppliers" (not t

It just occurred to me to look at this issue differently. I have read that one reason municipalities demand building permits is that they can up the value of a property based on the improvements and
I was just asking out of curiosity. People sometimes complain that a tower will lower their property values, so I was wondering whether there were any cases of towers doing the opposite. 73 Alan NV8A
US Tower called on Monday to say that my HDX-555 tower was complete and ready to ship. They said it could take a week for the trucking company to pick it up, but it was picked up in Kansas Wednesday
I don't know the current prices for Trylon and AN Wireless towers, but before my XYL convinced me that I was too old for climbing and urged me to get a tilt-over crank-up, I had come to the conclusio
I ordered my AlfaSpid at Dayton 2005. The additional shipping charge was somewhat higher than the original estimate, but I do not recall anything about a customs fee. The whole amount showed as a sin
US Tower offers only 2" masts and a thrust bearing for a 2" mast, but since each tower is built as the orders come in, they could no doubt build one with holes large enough for a 3" mast -- but you m
I did see your previous message, but I assume that nobody had an answer. Could it be an older US Tower model? 73 Alan NV8A _______________________________________________ ____________________________
The winch on my HDX-555 is the only one of which I have experience, so I too was surprised at the screeching noise when lowering (i.e., tilting down) the tower. But closer examination showed that the
Raising as well as lowering? Mine screeches only when I am letting the cable out: when I am tilting the tower up (winding the cable in), I just get the clicking sound of the pawl and ratchet mechanis
When I examined the winch on my HDX-555, it seemed that the brake mechanism applied permanent friction between the shaft and the toothed wheel, but when the cable was being wound in the pawl allowed
The originals are called Kellem Grips or simply Kellems, but there are various clones around. I have found them at Crescent Electric (not in every US state, but locations all over the place), also at
One of our club members recently bought a new notebook PC that came with Vista preinstalled, only to find that some of his old hardware and software no longer worked. A few days later he found himsel
